The ALICE Collaboration has measured the azimuthal correlation between trigger isolated-prompt photons and associated charged hadrons in Pb-Pb collisions at the CERN LHC, at a centre-of-mass energy per nucleon pair of $\sqrt{s_{\rm NN}} = 5.02$ TeV. The trigger isolated-prompt photons are measured in the transverse-momentum range $18 < p_{\rm T}^\gamma < 40$ GeV/$c$ and pseudorapidity range $|\eta^\gamma| < 0.67$. [...]

Results from a one-dimensional femtoscopic analysis of ${\rm K}^{0}_{\rm{S}}-{\rm K}^{0}_{\rm{S}}$ correlations in Pb$-$Pb collisions at the center-of-mass energy $\sqrt{s_{\mathrm{NN}}}~=~5.02$ TeV using data collected by the ALICE experiment at the LHC are presented. The source radius $R$ and correlation strength $\lambda$ are studied as a function of centrality and pair-transverse momentum ($k_{\rm T}$) to provide insight into the space-time structure and composition of the particle-emitting source.

Multiplicity dependence of prompt and non-prompt $\boldsymbol{\mathrm{J}/\psi}$ production at midrapidity in pp collisions at $\mathbf{\sqrt{\textit{s}} = 13}$ TeV
/ Ali Hassan Abdallah, Dana (Wayne State U.) ; Abualrob, Ibrahim Jaser (Houston U.) ; Acharya, Shreyasi (INFN, Bari) ; Agarwal, Kshitij (Trieste U. ; INFN, Trieste) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahuja, Ishaan (Kosice U.) et al.
The yields of prompt and non-prompt ${\rm J}/\psi$ and the fraction of non-prompt ${\rm J}/\psi$ are measured at midrapidity ($|y|<0.9$) via the dielectron decay channel as a function of the midrapidity charged-particle multiplicity ($|\eta|<0.9$) in pp collisions at $\sqrt{s} = 13$ TeV. The ${\rm J}/\psi$ yields and the multiplicity are normalized by their average value in inelastic collisions. [...]

/ALICE
The interaction between nucleons and hyperons -- baryons containing a strange quark -- is key to understanding the properties of dense nuclear matter, such as that expected in the interior of neutron stars. Direct scattering experiments are hindered by the short lifetime of hyperons, prompting the study of hypernuclei -- bound states of nucleons and hyperons -- as an alternative approach [...]

Dijet invariant mass of charged-particle jets in pp and p$-$Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV
/ Ali Hassan Abdallah, Dana (Wayne State U.) ; Abualrob, Ibrahim Jaser (Houston U.) ; Acharya, Shreyasi (INFN, Bari) ; Agarwal, Kshitij (Trieste U. ; INFN, Trieste) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahuja, Ishaan (Kosice U.) et al.
The ALICE collaboration presents the first measurement of the dijet invariant mass spectra of charged-particle jets in pp and p$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV. Charged particles in the mid-pseudorapidity region, $|\eta|<0.9$, are clustered into jets using the anti-$k_{\rm T}$ algorithm with a resolution parameter $R=0.4$. [...]

The first measurement of the elliptic flow coefficient of (anti)${}^3_{\Lambda}$H and the study of the $v_2$ of $^3\overline{\mathrm{He}}$ measured in Pb$-$Pb collisions at $\sqrt{s_{\rm NN}} = 5.36$ TeV with the ALICE detector are presented. Based on the large data sample of approximately five billion events collected in 2023 during the LHC Run 3 data taking, these measurements provide important insights into the production mechanism of (anti)(hyper)nuclei, as well as into the phase-space distributions of nucleons and hyperons produced in heavy-ion collisions [...]

This article reports the measurement of the transverse-momentum ($p_\mathrm{T}$) differential production cross section of $\mathrm{B^0}$ mesons in proton$-$proton collisions at a centre-of-mass energy of $\sqrt{s}=13.6~\mathrm{TeV}$ with the ALICE detector at the CERN LHC. For the first time, the $\mathrm{B^0}$ production cross section is measured at midrapidity ($|y|<0.5$) down to $p_\mathrm{T}=1~\mathrm{GeV}/c$ at LHC energies. [...]

/ Ali Hassan Abdallah, Dana (Wayne State U.) ; Abualrob, Ibrahim Jaser (Houston U.) ; Acharya, Shreyasi (INFN, Bari) ; Agarwal, Kshitij (Trieste U. ; INFN, Trieste) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahuja, Ishaan (Kosice U.) et al.
The first measurements of the average transverse-momentum fraction ($\langle z \rangle$) as a function of transverse momentum ($p_{\rm T}$) for strange baryons ($\Lambda$ and $\bar{\Lambda}$) and strange mesons (K$^0_{\rm S}$), produced in mini-jets defined through angular correlations in pp collisions at $\sqrt{s}=13$ TeV, are reported by the ALICE Collaboration at the LHC. The observable is obtained using a novel method, where the angular correlation between the strange hadrons and inclusive charged hadrons is weighted by the $p_{\rm T}$ of correlated particles at small angular distance.

The ALICE collaboration reports the azimuthal-anisotropy coefficient $v_2$ of prompt D$^0$, D$^+$, D$_{\rm s}^+$ mesons and the first measurement of $v_2$ of prompt $\Lambda_{\rm c}^+$ baryons in semicentral Pb$-$Pb collisions at a center-of-mass energy per nucleon pair of $\sqrt{s_{\rm NN}} = 5.36$ TeV. The D mesons and $\Lambda_{\rm c}^+$ baryons are reconstructed in their hadronic decays at midrapidity ($|y| < 0.8$) in the transverse-momentum interval $0.5 < p_{\rm T} < 24$ GeV/$c$ [...]
